DEMOUNTABLE RIM.

Specification of Letters Patent.

Application filed May 14, 1918. Serial No. 234,522.

To, all whom'z't may concern Be it known that I, J osnrn L. BREDAR, a citizen of the United States, residing at Rock Island, in the county of Rock Island and State of Illinois, have invented a new and useful Demountable Rim, of which the following is a specification.

The device forming the subject matter of this application is a demountable rim and one objectof the invention isto provide a rim of the type specified, comprising but three parts, the construction being such that the rim may be folded up readily within the area of a half circle-of which one of said parts constitutes a portion.

Another object of the invention is to pro vide novel means for operatively connecting together against movement, the ends of-two segments or part of the rim.

A further object of the invention is to improve. the construction of the joint be- .tween the relatively movable ends oftwo parts of the rim.

It. is within the'province of the disclosure to improve generally and to enhance the utility of devices of that type to which the present invention appertains. With the and a rim embodying the present invention;.

Fig. 2 is a fragmental flange showing a portion of the rim, the inner side thereof being depicted; Fig.3 is a section taken approximately' on the line 33 of Fig. 2; Fig. 4 is a section taken approximately on the line H of Fig. 2; Fig. 5 is a bottom plan showing the securing element which carries the latch.

In carrying out the present invention,

there is provided a rim comprising an intermediate segment 1 and terminal segments 2 and 3 hinged at their outer ends as shown at 4 to the ends of the intermediate segment, the inner ends of the terminal-segments be ing disposed in cooperating relation and be ing disposed approximately opposite to a point 5 'inidwa'y between the ends of the inn termediate segment 1. The construction is such that the terminal segments2 and 3' may I be folded toward the intermediate segmentl to lie within the area of a half-circle of which the intermediate segment -1 consti- Patented Oct. 14, E919.

meeting ends of the side flanges 7 of the segv ments 2 and 3 are beveled at an angle to the meeting ends 8 of the bases of the segments 2 and 3, as shown at 9.

A tongue 10 is secured to the base ,6 of the segment 3 and overlaps the base of the segment 2 as clearly shown in Fig.3, the tongue. having an outwardly extended projection '11 received in a recess 12 in the base tlof the segment 2.

A securing element isproVided, the same including a stem 14, a body 15 having parallel sides 16,'and a head 17 which projects laterally beyond the body 15. The stem 14 ow the securing element is mounted in the base 6 of the segment 2. The invention com prises a latch 18 mounted for right-line sliding' movement on the segment 2'and adapted to overlap the segment-3. The latch 18 has a longitudinal slot 19 in which. the body 15 of the securing element is received and because the body of the securing element is provided with parallel sides 16 which coact with the straight sides of the slot 19, the latch 18 is uided for right-line movement. The head 1? of the securing element overhangs the latch 18 and holds the same on the segment 2 for right-line movement as aforesaid. Adjacent its rear end, the latch 18 is dented or otherwise constructed, as shown at 20, to form a projection 21 coacting with a seat 22 fashioned in the base 6 of the segment 2. The latch 18 is independent of the tongue 10.

In practical operation, the segment 3 is swung outwardly into circumferential alinement with the segment 2, the projection 11 on the tongue 10 being received in the recess 12.0f the segment 2. Tiese elements coact to prevent relative circumferential movement between the segments 2 and 3 of the rim. The latch 18 is then slid end wise, until it overlaps the segment 3, and

thus, the segment 3 is prevented from swing ing inwardly with respect to the part 2-, ,the projection 21 being received in the seat 22 to prevent the rearward movement of the latch 18 and a disengagement of the latch from the part 3.

Attention is directed to the fact that, since the bases 6 of the segments 2 and 3 at their meeting ends are disposed radially of the rim, and since the side flanges Z are cut off at a bevel, as shown at 9, the structure will remain locked in a circle, even though it is not-mounted on a wheel.

The construction of the rim is such that it may be readily assembled. with and de tached from a tire, which is denoted by the numeral 23 in Fig. 1.

Having thus described the invention, what is claimed is 1. In a device of the class described, a rim comprising a plurality of pivot-ally connected segments each including a base and side flanges, the meeting ends of two of said segments having relative movement parallel to the median plane of the mm, the meeting ends of the bases of said two segment being disposed radially oi the rim, and the .meetmg ends of the side flanges of said two "segments being beveled at an angle to the meeting ends of the bases of said two segintense ments, and means for releasably connecting which have relative movement parallel. to-

the median plane of the rim; a tongue on 'one part and extended beyond the end of said part, to overlaptthe end of the other part, the tongue having a projection, and

said other part having a recess in which the projection is received; a latch independent of the tongue and slidable on said other part and adapted to overlap the end of the first specified part, the latch having a longitudinal. slotprovided with parallel edges; and a securing element including a stem mounted in said other part, a body having parallel sides coacting with the edges of the slot to constrain the latch for right-line sliding movement on said other part and to hold the latch out of the path of the tongue, the securing element including a head overlapping the outer face of the latch on opposite sides of the slot.

In testimony that I claim the foregoing as my own, I have hereto affixed my sig nature in the presence of two witnesses.
